Battled this issue for half a year. GM has finally released a bulletin for those of you that run into this problem. My local dealer seems to be a joke as they handed me this TSB, told me no solution, GM will not replace the radio, and we cant fix it. Good Luck.
Manged to fix it myself in the parking lot following the directions in attached document.
I hope it saves someone a lot of frustration and BS with dealer back and forth!
